Unico S1000 Visible Spectrophotometer

Yes, the Unico S1000 incorporates a key safety feature to ensure durability, especially in educational settings:

• Positive Safety Stopper: A positive safety stopper is integrated with the wavelength dial.
• Internal Protection: This “student-proof” mechanism prevents accidental over-rotation of the dial, which protects the internal monochromator and grating system from damage.

The Unico S1000 Visible Spectrophotometer operates across the visible spectrum, with a wavelength range of 400 nm to 1000 nm.

This broad range is suitable for a variety of general lab applications and educational experiments, including Beer-Lambert law testing, chlorophyll analysis, and protein assays.

Yes, the Unico S1000 offers excellent versatility in sample handling, accepting both round optical glass test tubes and standard 10 mm path length square cuvettes.

This compatibility makes it highly adaptable for diverse laboratory protocols, especially in educational and general testing environments.

For immediate use, the instrument is shipped complete with the following accessories:

• A box of twelve 10 mm test tube cuvettes.
• A 10 mm square cuvette adapter.

Yes, the Unico S1000 is designed for easy data handling and integration. It features an integrated USB interface specifically for simple data collection and transfer of analytical measurements to a computer. All measurement results (Transmittance: 0 - 100% T, Absorbance: 0 - 1.99 A) are also displayed clearly on the unit’s large digital display.

Yes, the Unico S1000 Visible Spectrophotometer is equipped with a high-performance tungsten halogen lamp. This reliable light source ensures consistent and stable illumination across the unit’s full operational wavelength range of 400 nm to 1000 nm, supporting precise and accurate results for a variety of laboratory and educational applications.

The Unico S1000 Visible Spectrophotometer operates with a fixed bandpass (slit width) of 20 nm.

This specific slit width provides the necessary spectral resolution for general laboratory testing and use in educational settings, covering the visible light range from 400 nm to 1000 nm.

The Unico S1000 Visible Spectrophotometer comes with several essential items, ensuring it’s ready for immediate use:

• 12 standard 10 mm test tube cuvettes
• A 10 mm square cuvette adapter for versatile sample handling
• A protective dust cover
• The user manual

The spectrophotometer also features an integrated USB port for convenient data collection and readout on its large digital display.

Yes, the Unico S1000 is engineered to enhance measurement accuracy by effectively minimizing stray light interference.

• Built-in Secondary Filters: The instrument utilizes built-in secondary filters specifically designed to reduce stray light, which directly improves measurement precision.
• Performance Specification: This feature allows the S1000 to maintain a low stray light specification of 2% T at 400 nm, ensuring reliable and accurate analytical results across its visible wavelength range.

Yes, the Unico S1000 is built to be rugged, incorporating a key protective feature essential for high-use environments like student laboratories:

• Positive Safety Stopper: The unit features a “student-proof” positive safety stopper integrated with the wavelength dial.
• Component Protection: This mechanism prevents the dial from being adjusted past safe limits, safeguarding critical internal parts like the monochromator and grating from potential damage.

Yes, the Unico S1000 is specifically designed as a rugged and robust instrument suitable for demanding educational environments like high schools and colleges.

Key features contribute to its durability and safety:

• Rugged Construction: It is engineered for repeated use and general laboratory testing.
• Monochromator Protection: It features a unique, “student-proof” positive safety stopper integrated with the wavelength dial. This prevents accidental over-rotation, thereby protecting the critical internal monochromator and grating components from damage.
